What CyrusOne does, and what this map holds

Designs, builds and operates data centers, leasing hyperscale and build-to-suit capacity to large tenants, with enterprise colocation secondary. It also does colocation, build-to-suit development, high-density AI capacity. This map identifies 62 data centers operated by CyrusOne across 12 states and 28 cities. Its largest presence is Texas, with 19 buildings.

After Texas, CyrusOne has the most data centers in Virginia (12), Ohio (6), Illinois (5), New Jersey (4), Arizona (3). Each state below links to that state's own page, which carries every operator in it, the grid operator, and the moratorium, water and delay record that applies there.

Disclosure is uneven and this page does not paper over it. 31 of the 62 publish a floor area, and 30 publish a power figure. Each figure is shown against the building it belongs to and never added into a single total, because operators do not measure the same thing: one states the floor area of one hall, another the full capacity of a campus it has only announced.

PeeringDB records networks meeting in 18 of these buildings, 94 network presences in total. That is a measure of how much traffic exchanges inside the building, not of its size.

4 of these records are marked planned, permitted or under construction rather than operating, and each is labeled as such in the list below.
